CAR-WINDOW LOCK.

SPECIFICATION forming part of Letters Patent No. 350,418, dated October5, 1886.

Application tiled May Q4, ISES. Serial No. 203,080. No model.)

To all whom it may concern:

Be it known that I, MARTIN A. CUTTER, a citizen of the United States,residing in Galveston, in the county of Galveston and State of Texas,have invented certain new and useful Improvements in Car-Window Locks,of which the following is such a full, clea-r, and exact description aswill enable others skilled in the art to construct the same, referencebeing had to thc accompanying' drawings, and to letters of referencethereon, the same letter indicating a like part in each of the figures.

Figure l represents an elevation of a carwindow with my improved lockattachment, illustrating the method of operating the same. Fig. 2 showsthe inside of the lock, one of the side plates being removed, the partsoccupying the position they are in when locked. Fig. 3 is a similar viewto show the parts in the position they occupy when unlocked. 4 and 5 aredetails, and Fig. 6, a plan of t-he sheet of metal forming the case asit comes from the dies before being bent to shape.

This invention relates to improvements in the carwindowfastening devicefor which Letters Patent of the United States were granted to me on the19th day of January, 1886, being No. 334,692, the object being to add tothe devices therein shown for supporting the window, a positive lockingdevice by which the window is secured while the cams hold it in positionat any desired point, and are operated, as well as the bolts, by thean-v nular handle and connecting devices shown in the above-namedpatent.

The invention may therefore be said to consist in the combination,withspring-operated cams attached to the sash for holding the same at anydesired height, and suitable operating devices, of a locking-bolt movedby the'opera-ting devices simultaneously with the movement of the'cams,as hereinafter clearly described, and specifically pointed out in theclaims.

The case A is preferably of sheet metal cut to the desired form, asshown in Fig. 6, and then bent on the dotted lines crossing the same tomake the front and sides of the case, as shown in Figs. et and 5. Bythis means a strong and cheap case is'produced, and which readily admitsthe introduction of the holding receives one end of the coiled springc5, the

opposite end of said spring resting against the wood of the sash orother suitable support. The tendency of this spring a5 is therefore tocontinually push forward the cam-bar, causing its serrated face c" toproject through the opening a2, and engage with the adjacent sides ofthe window fraine,with which it remains in contact, except .when thewindow is being raised or lowered. To allow of its with` drawal at suchtimes, the pivot-pins AaT are passed through the curved slots a3 andscrewed into the projections c of the cam-bar a. These. pivot -pins areconnected by the rods c with the annular handle c, the rotation of whichin one direction will simultaneously withdraw the cams from theircontact with the frame at both sides of the window, allowing the latterto be raised or lowered by the same hand that grasps the handle, leavingthe other free for other uses, as fully set forth inA the patenthereinbefore named. As these cams could not be depended upon to lock thewindow in position when down, it became desirable to add to the same alocking device which should securely lock the window in place, but mightbe operated simultaneously with and by the same operating-handle thatactuated the cams. This I have accomplished by adding to the mechanism abolt, b. This bolt is carried at one end in an orifice of the plate, asb, and at the other in a similar oriiice in the bar b2, which extendsacross the space between the two sides of the case. This bolt b has theform of a crank, the part representing the crankpin being the part whichacts as a bolt in locking,while the body forms a guide and carries thespring b3, which is coiled around it between the bar b2 and the shoulderformed by the crankarm at b". This spring always tends to force the boltoutward and retain it in that position. Therefore, to cause it to lockthe window automatically, it is only necessary to form suitable orificesin IOO the frame, as d, preferably metal-lined, to receive the bolts atsuch points as it is desired to lock the window.

In order to withdraw or unlock the bolt, the upwardly-projecting end ofthe cam is carried up until it bears `on the part b* of the bolt, fromwhich it will be evident that as the cam is moved by the annular handleits action upon the crank-arm of the bolt will cause the latter to bewithdrawn from the orifice in the frame and allow the window to beraised or lowered without difficulty.

It will be apparent that this window-fasten ing,` device may be appliedto other than carwindows, as its construction allows of its applicationto almost any sliding` sash.

Having thus described myinvention, I claim as new and desire to securebyLetters Patent the following:

1. As an improvement in car-window locks, the sliding` crank-shapedspring-actuated bolt b for locking the window, in combination with theoscillating` cam a, acting upon the bolt to unlock it, said cam having alateral arm with a spring-guide hinged thereto, a spring surrounding theguide, and means for swinging the cam and thus retraeting the bolt, allarranged and operating,` substantially as specified.

2. In a car-window lock, the bolt and cam support thrown outward bysprings, in combination with the annular handle, and conneetions forwithdrawing the bolt and cam arranged and operating in the manner shownand described.

In testimony that I claim the above as my invention I hereunto affix mysignature in the presence of two witnesses.

M. A. CUTTER.
